Now that we know what /n means, the rest of this article will walk you through everything you need to know about printing new lines in Python to make sure your program’s output is properly formatted and readable. As you can see from the output of the for loop used to print each cha...

KMeans Python 实现 距离计算函数 质心函数 聚类函数 算法验证 函数编写完成后,先以 testSet 数据集测试模型运行效果(为了可以直观看出聚类效果,此处采用一个二维数据集进行验证)。testSet 数据集是一个二维数据集,每个观测值都只有两个特征,且数据之间采用空格进行分隔,因此可以使用 pd.read_table() 函数进行读取。

- y: A numpy array f shape (N,) giving training labels; y[i] = c means that X[i] has label c, where 0 <= c < C. - X_val: A numpy array of shape (N_val, D) giving validation data. - y_val: A numpy array of shape (N_val,) giving validation labels. - learning_rate...
```python sample_means = [] for n in [5, 10, 20, 50, 100, 1000]: means = [np.mean(np.random.choice(uniform_data, n)) for _ in range(1000)] sample_means.append(means) ``` 四、绘制直方图 现在我们已经得到了不同样本大小下的样本均值,接下来我们可以绘制直方图来观察样本均值的分布情...
